Subject: Add Hash::Merge exception to the leak test
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=307ab4c58566698710b71eebbfb612686d9133be;p=dbsrgits%2FDBIx-Class-Historic.git

Add Hash::Merge exception to the leak test

This is so that a user with a DBIC_TRACE_PROFILE in the env will
still be able to pass the tests/install
